Thanks a lot for pointing me to the relevant features and documentation
and for providing so much context. That really helped to improve
mandoc PostScript output.
See below for what i committed to -current. It would be quite
welcome if Jan could test on his multi-tray printer that the printer
actually selects the right paper for different -Opaper= options
now, and that there are no errors or warnings.

No problem, so no changes seem to be required to PDF output.

No, that is still broken in 6.2, i only fixed it post-6.2.
Thanks again,
Ingo

-----------
Print a human-readable media name in the %%DocumentMedia DSC comment
and use the setpagedevice PostScript operator to help printers
automatically select the paper of the best matching PageSize.
Many thanks to Mike Williams <obsd1 at eandem dot co dot uk>
for teaching me about the relevant features of PostScript and DSC
and for suggesting what to put into the first %%DocumentMedia argument.
